How long for halides to burn in?

[Jase]

Just upgraded my tank and lighting, and now have two Hamilton German 10,000k, and 2 96 w pc blues.

First does anyone know if these are the same bulb as the Ushio?

Second , how long do they take to burn in, mine look kinda yellow at the moment.

Give 'em about a week to 10 days--they'll settle in. When I put MH on my tank, one looked kind of purplish and the others were more blue. After a couple of weeks, they all matched. I think the general rule is around 100 hours of burn time for them to really settle in.

Can't comment on your other question.

Not sure about your particular bulbs, but my 6500K Iwasakis have little glass nipple things on the arc tubes. If yours do, make sure they are pointed up as this is the correct orientation and has significant impact on the colour of the light.

Yup, 100 hours is about right.

anyone know if other bulbs have this nipple thing?

AFAIK, all mogul-based bulbs will have a nipple on the inside envelope.

Hamilton Technology is a manufacturer. I have the Ushio 10K 250W bulbs, the package definitely says Ushio on it, and made in Germany, but cant remember if the manuf. was Hamilton or not. Maybe someone else knows- otherwise I will look tonight and get back 2 you.

Ushio is the manufacturer, Hamilton is having them made OEM with their markings on them.

Ushio and Hamilton are the same, Aqualine-Bushke are different.
